SEPARABLE LINK-BUTTON.

SPECIFICATION forming part of Letters Patent No. 769,334, dated September 6, 1904.

Application iiled May 270, 1904. Serial No. 208,862. (No model.)

ToA a/ZZ. whom, it 17m/y con/cern:

Be it known that LFRANK P. BARNEY,a citizen of the United States of America, and a resident of Chartley, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Separable Link-Buttons, of ywhich the following is a specification.

This invention relates to separable link-buttons for cuffs-that is, link-buttons comprising two separable members; and it consists, essentially, of a button or head provided with a hollow post or shank having a fixed springlink extending therethrough longitudinally, the outer or free end of which is cut transversely and bent to form a spring eye or loop, combined with a fellow button or head having secured to its under side an eye capable of being readily introducedv into or detached from said spring-loop at will.

In separable link-buttons embodying the present improvement the uservis enabled to manipulate them quickly and with great facility in the process of application and removal or separation.

Another advantage is that by reason of its simplicity the cost of manufacture is materially reduced. It may be added that the device is not liable to get out of order, and when in use the buttons are practically locked together, thus preventing accidental separation and possible loss of the parts.

lIn the accompanying sheet of drawings, Figure l is a front or Side elevation, on an enlarged scale, representing the normal relation of a pair of linked buttons embodying my improvement. Fig. 2 isa front view of the spring-link detached from the button. Fig. 3 is a side view vsimilar toFig. l, but showing the relatively movable head member in the act of being introduced or linked to the other member. Fig. I is a similar'view showing the manner of detach ing the two buttom inembers or disconnecting them. Figs. 5 and 6 are transverse sectional views, enlarged,taken,

respectively, on lines 5 5 and 6 6 of Fig. l. Fig. 7 isa longitudinal central sectional view showing a modied form of the hollowrpost or shank, and Fig. 8 isa plan view of the same.

A in the drawings designates my improved separable link-button as a whole. To the back or under side of the relatively stationary head or button member CZ is secured in any suitable way the hollow post or shank a. I prefer to make flat and also bent or curved longitudinally of its axis,l its outer end a2 being well rounded and slotted transversely at a. The other or fellow button member c.

has a short closed eye c extending from its under side.

The link proper, b, consists of a piece of suitable spring-wire or material bent subtantially as represented in Fig. 2. One end,

L2, is adapted to be secured to the bottom of said post, the 'other end being enlarged to form the eye or loop The two end por-` tions e e of the wire is beveled and Abrought together at one side of the loop to form a normally closed joint athat is to say, the

elasticity or resiliency of the link automatically presses the end or arm e in lyielding engagement with the other end, e', thereby-keeping them in normal contact with each other.

The link b is inserted in the post a and is secured therein in any suitable manner. A simple and effective way when a at post is used is to indent the two sides of the latter at a .point oppositethe bend o2, thereby producing short projections a3, which extend into 8O the corresponding space. (See Fig. 6.) In assembling the parts the loop including the abutting end portions e e", extend through the post, as clearly shown.

The operation of attaching and detaching the button c to and -from the link 6 is very `easily and quickly effected. The face of the eyec of button c is placed lbelow the joint a and pressed ahead (in the arrow direction,

Fig. 3) against the movable end e ofthe link 90 until the latter opens inwardly sufhciently to admit the eye c, at which instantv the said end e springs back again into place, thus securing or locking the buttons together, substantially as represented in Fig. l.

ofthe operation the other portion of the loop t remains stationary. In order to detach the button e, the eye of the latter iS-pressed against the inner free end portion e of the loop and above the joint, (see Fig. 4,) thereby 100 This latter 55 During this part springing the loop inwardly and carrying its end c' outwardly beyond the then stationary part c, thus producing an opening for the passage of the buttons eye, after which the loop portion of the link springs back into its normal position. p

In lieu of the flat and curved post I may use a straight round hollow one, as represented in Figs. 7 and 8. Otherwise the construction and arrangement of the parts are substantially as represented in Figs. l to 4. Instead of indenting the post or inserting a pin transversely through it to hold the link I) in position therein the end b2 of the latter is soldered to the back of the adjacent button d, as indicated at s, Fig. 7.

It is obvious that the shape and size of the button members c and CZ, as well as the style of ornamentation and settings used, are in no wise affected by the employment of my improvement. It will be seen, too, that in the manner of opening the joint 1t of the loop of the spring-link for the insertion or re- Y moval of the button c the same is effected by simply pressing the button itself in the proper direction against the corresponding yielding ends e e', as before described. I deem this a valuable feature of the invention.

I claim as new and desire to secure by United States Letters Patentl. In a separable link-button provided with a front or head member and a post rigidly secured thereto,the combination therewith of a fellow head member c having an eye on its under side, and a link or connection b mounted in said post, said link having' a severed spring eye or loop portion extending beyond the post, into which loop the eye of said member c is hooked.

2. As an improved article of manufacture, 40

the separable link -button, substantially as hereinbefore described, the same consisting of a head or button al, a hollow post (1/ secured thereto, a movable head or button c having an eye on its under side, and aspring-link 7 having a severed self-closing loop b', the link being mounted in said post and having its loop portion exposed to freely receive the eye of the button c.

3. In a separablelink-button provided with a pair of heads or button members, al c, the combination therewith of a hollow post rigidly seoured to said member d having oppositely-disposed notches formed in its outer end, a spring-link suitably mounted in the post and in engagement with said notches and provided with a cnt loop adapted to receive an eye formed on the under side of said button c, substantially as described.

4. In a separable link-button provided with a pair of oppositely-disposed heads or button members, one of which has an eye c on its under side, the combination therewith of a suitably-mounted spring-lilik, normally stationary or iiXed with relation to the other button member, having its outer portion formed into a transversely-divided self-closing loop the adjacent ends thereof being resilient, and having` the eye of said button member detachably connected to the loop portion of said link.
